Senior QA Engineer who built reusable Playwright and TypeScript frameworks for client accounts.

Message

At MuukTest, I designed, developed, and maintained reusable Playwright and TypeScript frameworks with Page Object Model for client accounts. They covered end-to-end and integration flows and reduced manual regression effort.

I analyzed application behavior to design test cases, often with limited documentation, and tackled challenges including dynamic selectors, iframes, and data-driven tests using XLSX.

For a client, I tested REST APIs with Postman and Swagger/OpenAPI, validated token-authenticated endpoints, and used SQL for data validation. I also integrated automated tests into CI/CD pipelines through YAML configuration in collaboration with DevOps.

Earlier, I tested the coppel.com e-commerce platform across web and Android, including its V7-to-V9 migration. I’ve also worked as a Requirements Analyst and Scrum Master, and hold ISTQB Certified Tester Foundation Level certification.
